Washington Gas Energy Systems Expands Footprint Across the Country and Announces Completion of Two Solar Arrays at California Educational Institutions

MCLEAN, Va.--(BUSINESS WIRE)--
Washington
Gas Energy Systems, Inc. today announced the completion of two solar
projects that will generate renewable energy for Western
University of Health Sciences in Pomona, Calif. and Corcoran
Unified School District in Corcoran, Calif. The company will hold
two separate ribbon cutting ceremonies this week to celebrate the
completion of the solar arrays. Both facilities will be owned and
operated by Washington Gas Energy Systems under 20-year power purchase
agreements. Washington Gas Energy Systems is a subsidiary of WGL which
offers a diverse set of energy sources including natural gas, wind, and
solar as well as a range of energy solutions - generation, storage,
transportation, distribution, supply, and efficiency - which serve
customers in more than 25 states.

"Dedication to pursuing renewable energy options set Western University
and Corcoran Unified School District apart as forward-thinking
organizations focused on reducing their environmental footprints," said
Sanjiv Mahan, chief operating officer of Washington Gas Energy Systems.
"We are committed to working with educational organizations across the
country on projects like these and are eager to maintain this positive
trend with other institutions. These projects alone will reduce
greenhouse gas emissions equivalent to taking 476 cars off the road each
year."

The solar array at Western University will be unveiled at an event held
at the school today. The 672-kilowatt, campus-based project consists of
a roof-mounted system composed of 2,688 solar panels affixed to three
buildings, and a carport system with solar panels located at one of the
parking areas. It is expected to generate approximately 1,110 megawatt
hours of solar energy per year. Green
Energy Partners developed the project; Conergy
managed engineering, procurement and construction.

"Western University welcomes this opportunity to help the environment,
reduce the impact of our operations, and lower our electrical costs,"
said Thomas G. Fox, the university's senior vice president. "Solar
panels offer a simple solution, one that makes a strong statement about
the importance of a greener planet for a healthier life."

Corcoran Unified School District will unveil its 1,269-kilowatt solar
project in a ribbon cutting ceremony on Friday. The solar array consists
of 4,422 solar panels that span seven sites throughout the school
district, including ground-mounted and carport systems at Bret Harte
Elementary, the Corcoran Administration Building, Corcoran High School,
Fremont School, John Muir School, The Learning Center and Mark Twain
School. The project is expected to produce 2,125 megawatt hours of solar
energy per year, which will cover approximately 88 percent of the school
district's electricity needs. The project was developed by AMSOLAR
and was engineered and installed by Conergy.
TerraVerde
Renewable Partners acted as the consultant for the district.

"Corcoran Unified School District has become known as a district that
leads in technology," said Rich Merlo, superintendent of Corcoran
Unified School District. "This solar project is an example of how using
technology can improve our lives and provide opportunities for people,
just as we in the district have made a commitment to everything
conceivable to use modern technology to open the possibilities for our
students and community!"

Each project is expected to significantly reduce greenhouse gas
emissions produced by the schools. The Western University array is
expected to reduce emissions equivalent to recycling 293 tons of waste
instead of sending it to a landfill each year.

"This solar project will result in a significant cost savings for
Western University over the next 20 years, allowing the school to focus
funds on other initiatives," said William DePhillipo, founder of Green
Energy Partners. "Predictable energy rates coupled with a reduction in
greenhouse gas emissions makes this an example of the viability of
renewable energy for other universities across the country."

The Corcoran Unified School District project will help reduce greenhouse
gas emissions equivalent to taking 312 passenger cars off the road each
year.

"One of the great things about working with a District like Corcoran is
its commitment to new technology, in both the classroom and in improving
operations," said Dr. Rick Brown, president of TerraVerde Partners.
"With our help, the District took a very sophisticated approach to
evaluating the costs and benefits of new technologies, and an
expert-managed competitive bid process in securing the best possible
market pricing for their solar project."
